Timers

Timers are electronic or electromechanical control devices used to introduce precise time delays in the operation of electrical circuits and automation systems. They control functions such as ON-delay, OFF-delay, interval, cyclic, or star–delta operations based on preset timing values. Typical technical features include wide time-setting ranges from milliseconds to hours, multiple operating modes, supply voltages such as 24 V AC/DC or 110–230 V AC, relay or transistor outputs with defined contact ratings, and compatibility with control panels, motor starters, and industrial automation applications.
